You have two numbers to work with 7 and 5.
To keep the ratios the same using different numbers they would have to increase or decrease by the same multiple.
The answers would be 5:12, 7:12 and 6:7 do not represent a ratio in the fridge.
Riley : 0.48/12 = 0.04 per bead
Magdalena : 1.00/20 = 0.05 per bead
15 beads...
Riley : 15 x 0.04 = 0.60
Magdalena : 15 x 0.05 = 0.75
15 of Riley's beads cost (0.75 - 0.60) = 0.15 cents less then 15 of Magdalena's beads
